Like all worth-while institutions, the American Escadrille, of which I have the honour of being a member, was of gradual growth. When the war began, it is doubtful whether anybody anywhere envisaged the possibility of an American entering the French aviation service. Yet, by the fall of 1915, scarcely more than a year later, there were six Americans serving as full-fledged pilots, and now, in the summer of 1916, the list numbers fifteen or more, with twice that number training for their pilot's license in the military aviation schools. The pioneer of them all was William Thaw, of Pittsburg, who is to-day the only American holding a commission in the French flying corps. Lieutenant Thaw, a flyer of considerable reputation in America before the war, had enlisted in the Foreign Legion in August, 1914. With considerable difficulty he had himself transferred, in the early part of 1915, into aviation, and the autumn of that year found him piloting a Caudron biplane, and doing excellent observation work. At the same time, Sergeants Norman Prince, of Boston, and Elliot Cowdin, of New York--who were the first to enter the aviation service coming directly from the United States--were at the front on Voisin planes with a cannon mounted in the bow. Sergeant Bert Hall, who signs from the Lone Star State and had got himself shifted from the Foreign Legion to aviation soon after Thaw, was flying a Nieuport fighting machine, and, a little later, instructing less-advanced students of the air in the Avord Training School. His particular chum in the Foreign Legion, James Bach, who also had become an aviator, had the distressing distinction soon after he reached the front of becoming the first American to fall into the hands of the enemy. Going to the assistance of a companion who had broken down in landing a spy in the German lines, Bach smashed his machine against a tree. Both he and his French comrade were captured, and Bach was twice court-martialed by the Germans on suspicion of being an American _franc-tireur_--the penalty for which is death! He was acquitted but of course still languishes in a prison camp "somewhere in Germany." The sixth of the original sextet was Adjutant Didier Masson, who did exhibition flying in the States until--Carranza having grown ambitious in Mexico--he turned his talents to spotting _los Federales_ for General Obregon. When the real war broke out, Masson answered the call of his French blood and was soon flying and fighting for the land of his ancestors.
